Uncharted Golden Abyss and the problem with plotholes

Hi,
     I just finished getting the Platinum Trophy Saturday. It's a decent game, considering the hardware it runs on, although I could do without all the touch functionality. The story is pretty forgettable, basically a mish-mash of Drake's Fortune, Among Thieves and Drake's Deception. It highlighted all the plot holes that Uncharted seems to have though. Drake also looked foolish several times in the game.

Spoilers ahead for most of the Uncharted games?

Please help.
Thanks!
I didn't find the right solution from the Internet.
